10x3+8=80-60+? 30+8=20+? 38=20+? 38-20=? 18=? The answer is 18.
2a+54=38 2a=38-54 2a=-16 a=-16/2 a=-8

No. Substitute the value 8 for x, and you have 4x +6 = 4(8) +6 = 32 +6 = 38.

No. Substitute the value 8 for x, and you have 4x +6 = 4(8) +6 = 32 +6 = 38.
22+16-8*5 = 38-40 = -2.
Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5
119. 8 plus 8 plus 8 plus 5 is 29 so you put the nine in the ones spot and you add the two with the 2,3,3 and 1. That equals 11 so you put the 11 in the tens spot.111111111199999 119
It is the property that equals plus equals are equals.
abc = 38
if -4x+6=38 what x=
That equals 28
